QUICK-ADJUSTABLE WRENCH.

Specificationof Letters Patent.

Patented Aug. 5, 1919.

Application filed December 1, 1917. Serial No. 204,839.

To all whom it may concern:

Be it known that I, WILLIAM LOUIS BnssoLo, a citizen of the UnitedStates, and a resident of San Diego, in the county of San Diego andState of California, have invented a certain new and useful Improvementin Quick Adjustable Wrenches, of which the following is a specification.

My present invention relates generally to wrenches, and particularly toone of that type having engaging jaws one of which is movable withrespect to the other, my improvements relating to the connection betweenthe parts brought about by their particular construction and relationwhereby the movable jaw may be quickly and accurately positioned withoutthe necessity of rotating parts and other more or less complicated andexpensive connections.

These improvements are preferably embodied in the construction as shownin the accompanying drawing, forming a part of this specification andwherein:

Figure 1 is a side elevation thereof.

Fig. 2 is a horizontal section taken substantially on line 22 of Fig. 1,looking in the direction of the arrow.

Fig. 3 is a similar view looking in the opposite direction, and

Fig. 4 is a vertical section taken substantially on line 4-4 of Fig. 1.

In the invention as thus shown, the rigid jaw 10 has its shank in twoparts, that part upon which it is directly mounted and as indicated at11, being threaded and extended through and engaged by an adjusting nut12, the latter of which is movably mounted within the cut-out portion ofan otherwise substantially solid adjusting bracket 13, to which theadjacent end of the other part 14 of the shank of the jaw 10 ispivotally connected at 15. The movable jaw 16 is slidably mounted uponthe portion 11 of the shank of the jaw 10 and is freely shiftable at alltimes between the jaw 10 and the upper or outer face of the adjustingbracket 18. It is obvious that in this construction, in which themovable shank 17 is pivotally connected at its outer end at 18 to themovable jaw and is provided with ratchet teeth 19 engaging similarratchet teeth 20 of the portion 14 of the jaw 10, the jaw 10 may besuitably spaced in the first instance, from the movable jaw 16 by virtueof its adjustment through the action of the adjusting nut 12 engagingthe threaded portion of the part 11 of its shank.

It is also obvious that the construction of the invention as thusexplained provides for more rigid manufacture as well as for greaterconvenience and effect in use.

I claim:

1. A wrench comprising a pair of shanks arranged to parallel one anotherand provided with relatively engaging ratchet teeth, a jaw rigidlydisposed at one end of said shanks, a aw pivotally connected to one endof the other shank and slidably engaging a portion of the shank of thefirst jaw, said shank of said rigid jaw being in two parts havingpivotal connections and means for adjusting one of said shank parts withrespect to the other.

2. A wrench comprising a pair of shanks arranged to parallel one anotherand one of which includes a portion having with the other shank,relatively engaging teeth, the other portion of said first named shankhaving a threaded section, an adjusting bracket having a rotating nutand through which and through said nut the threaded section of saidshank portion extends, a pivotal connection between the said adjustingbracket and the toothed portion of said shank, a jaw rigid with thethreaded portion of said shank, and a second jaw slidably adjustableupon the threaded portion of said shank between the said adjustingbracket and the said rigid head, and to which one end of the other shankis pivotally connected.
